3 Claims. (Cl. 20---52.2)

The present invention relates generally to window constructions, for residences and for industrial use, and more particularly to improvements in windows employing slidable sash members, which are economically fabricated of aluminum or similar light metal,in respectto which either of two sash members may be readily removed from a frame member without disassembly of either the sash or the frame, and in which the window is completely weather-tight, while sliding of the sash relative to the frame is noise-free, friction-free and wear free.

It is a broad object of the present invention to provide a sash window construction employing alight weight frame of generally rectangular configuration, which may be secured to a building, and within which may be inserted two sash members, without disassembly of either the frame or the sash members, and without tools, or special skills.

It is another object of the present invention to provide a novel window having a frame containing horizontally extending rails on which sash members may ride, located in the lower horizontal element of the frame, and channels in the upper horizontal element, having Walls between which the sash members may ride, the sash members riding on a nylon or similar bearing secured to the lower rail of the sash members, to minimize noise, friction and wear.

It is a further feature of the invention that all surfaces of the sash members which bear againsttheframe or any element thereof, are provided with wool pile bearing surfaces, the wool pile being secured toplastic strips, which are inserted by lengthwise sliding into slots in the sash members, for ease of construction and for weather tightness. p

Another feature of the present invention is that no bolts or screws are required in its construction.

It is a further feature of the invention that glass panes are locked to the sash members by means of resilient or deformable plastic locking strips, whereby glass panes may be economically inserted on initial fabrication, or readily replaced in event of breakage.

The above and still further objects, features and advantages of the present invention will become apparent upon consideration of the following detailed description of one specific embodiment thereof, especially when taken in conjunction with the accompanying drawings, wherein:

Figure 1 is a view in front elevation of a window in accordance with the invention;

Figure 2 is a view in section taken on the line 2-2 of Figure 1;

Figure 3 is a view corresponding with that of Figure 4, but employing a modified frame construction;

Figure 4 is a view in section, taken on the line 4-4 of Figure 1;

Figure 5 is a view taken on line 5-5 of Figure 4;

Figure 6 is a sectional view taken on the line 66 of Figure 4; and

Figure 7 is an expanded view in section taken on the line 7-7 of Figure 6.

Referring now more particularly to the accompanying drawings, the referencenumeral 1 denotes a rectangular frame, having an upper longitudinal element 2, a lower longitudinal element 3, and two vertical elements 4 and 5. The several frame elements are separately formed, and welded together on the lines 6. Nailing apertures 7 are provided through flange elements 8 of the frame, and facilitate mounting of the flange elements flush against a suitable openng in a building, themain body of the frame extending within the opening.

The lower horizontal frame element 3 includes two integral vertical rails, 10 and 11, which extend along the entire length of the element, parallel to one another, and transversely displaced by a distance greater than the thickness of a sash member. The upper frame member 2 includes a central vertically depending channel wall 12, which lies on a line mid-way between the rails 10 and 11; and a further vertically depending channel Wall 13 which is displaced from flange 12 on one side thereof by a spacing slightly greater than the thickness of a sash member, and extends parallel thereto.

Still another vertically depending channel wall 14 extends parallel to flange 13, on the opposite side of flange 12, and is spaced therefrom by the approximate thickness of a sash member. The vertically depending channel walls 12, 13 and 13, 14 form channels in the upper frame element 2, within each of which one of the sash members rides. The upwardly extending vertical rails 10, 11 are located approximately mid-way of the channels, respectively, and the sash members bear on and slide on these. The frame includes a vertically extending lip 15, aligned with wall 14, and the latter serves to outline the inboard portion of the frame, in conjunction with corresponding vertically extending lips 16 and 17. The rails 10 and 11 also include vertically extending correspondingly shaped lips in vertical frame members 4 and 5.

In Figure 3 of the drawing the external flanges 8 are shown replaced by pairs of lips 20, to permit abutted construction, i.e., between the lips 20 may be placed wood frame members which abut against the external approximately horizontal portions 21 of the frame which extend between the lips 20. In other respects the con struction of the frame of Figure 3 duplicates that of Figures l, 2, 4-7.

Two sash members, 22 and 23, are employed, which are left and right handed, respectively, but are otherwise generally similar, except in respect to latching elements. The latter include two co-acting or complementary latch components, 24 and 24a, one for each of sash members 22 and 23, and are per se conventional and therefore are not further described. They serve to latch the sash memberswhen the window is in closed condition, to prevent entry of unauthorized persons, or the like purposes.

Each sash member is fabricated of four extrusions, which form the sides of a rectangle Within which is placed a pane of glass. The extrusions are identified as follows: lower horizontal, 25; upper horizontal, 26; inner vertical, 27; outer vertical, 28.

The four extrusions 25-28, which form the basic elements of a rectangular sash member, are rigidly secured together at the corners of the rectangle, by means of a device which is illustrated in Figures 5 and 6. The device includes an angle member having two arms 30, 31 extending at right angles, which subsist, respectively, within slots 32 in adjoining sash elements, at the extremities thereof. The arms 30, 31 include notches 33 into which the material of a thin wall of the sash elements is peened, as at 34.

The arms 30 which subsist in the lower horizontal sash element 25 each includes a cut-out, 35, which permits insertion of a nylon bearing element 36. The latter is symmetrical with and rides on the vertically extending 3 rail, 11, and permits silent, friction-free wear-less sliding of the sash member.

Extending along the entire length of the lower horizontal sash element is a pair of parallel slots 39, 40, which face the rail 11 on opposite sides thereof, respectively. In each of slots 39, is inserted a-plastic or aluminum strip 41, from which extends a mass of Wool pile 42. The masses of wool pile 42 bear against the sides of the rail 11 and provide a weather-tight joint for any position of the sash member within the frame.

The upper horizontal sash element 26 includes external slots 44, 45, which extend along the entire length of the element parallel with channel walls 12, 14. Each of slots 44, 45 supports a plastic or aluminum strip 46, to which is secured wool pile 47. The Wool pile 47 bears against the channel walls 12, 14, on the interior Walls thereof, and provides weather-proofing at this part of the sash for any position of the sash with respect to the frame.

One of the sash members (see Fig. 2) includes afurther vertical strip of wool pile 50, which bears against a vertical bent lip 51 extending from the other sash element. The bent lip 51 bears against the wool pile 50 only when the window is wholly closed, and in this position provides weather-proofing at the junction of the sash members.

It will be apparent from the foregoing that the sash members are provided with weather-proofing elements, at every point of the circumference thereof. The weather-proofing strips, being in the form of wool-piled plastic strips which slide endwise into slots in the frame element, are easily assembled to the sash elements or extrusions before the latter are assembled to form a sash member. Thereafter, they are locked in place because the open ends of the several slots are blocked by adjacent sash elements.

The glass pane 50, for each sash member, is cut to fit within a frame formed by all the sash elements, and including internally extending lips 51 which extend inwardly of the sash member in the plane of the sash member, and further lips 52 which extend perpendicularly of the plane of the sash member. Extending around the interior of the frame of the sash member is a slot 53, having a relatively narrow entrance and a relatively wide interior, within which may be forced a vinyl plastic element 55, having an extension 56 which presses the glass pane 50 against the lip 51. in assembling the pane to the sash member the lip 51 is coated with glue at the face against which the pane impinges, and the pane is inserted. The vinyl element 55 is plastic, and is rolled into the slots 53 until it fills the latter, and also is rolled as at 56 to cover the glass pane 50 adjacent its edge. The pane 50 is thus positively locked in place. Should a pane require replacement the vinyl element 56 is sufliciently soft that it may be pulled out of slot 53, to enable removal of the pane, and replaced after a new pane has been inserted.

The sash members are readily inserted into or removed from said frame by providing sufiicient depth in the channels formed by channel walls 12, 13 and 13, 14, so that the sash members may be lifted from the rails 10 and 11 and thus readily removed for repair, replacement, cleaning, or the like.

Suitable weep-outs 60 are provided at suitable locations in the rails 10, 11 to permit egress of water from the channels formed by rails 10 and 11, Without affecting the weather-tightness of the structure, and relatively large ports 61 are provided in the outermost rail 10, which extend to the frame and provide egress ports for water which might otherwise collect between rails 10 and 11.

It will be noted that the sash is so spaced with respect to the rails and each other and the lip 15 that condensation, or moisture derived from rain or snow, may run off the windows and out of the Weep-outs 60 or the ports 61.

While we have described and illustrated one specific embodiment of our invention, it will be clear that variations of the general arrangement and of the details of construction which are specifically illustrated and described may be resorted to Without departing from the true spirit and scope of the invention as defined in the appended claims.

What we claim is:

1. A window construction including a frame member and a pair of sash members, said frame member having a lower horizontal element including an upwardly. extending rail substantially coextensive longitudinally with said lower horizontal element, at least one of said sash members including a lower horizontal element and vertical side elements, said elements of said sash having in their outer edge a channel having a cross-section with an enlarged region adjacent the bottom of said channel, a pair of angle members each having a pair of arms, one of said arms of each of said angle members being disposed in the enlarged region of said channel at a different end of said channel in said lower sash element and another arm of each of said angle members being disposed in the enlarged region of the channel in a different one of said vertical sash elements, said arms having a cross-section of approximately the same size as the crosssection of the enlarged region of said channels, said arms disposed in said channel in said lower sash elements each having a transverse recess in a surface remote from the bottom of said channel, a substantially frictionless, plastic insert disposed in each of said recesses, said inserts extending downwardly from said recesses into a lower region of said channel so as to be arranged to ride on said rail.
